Description

  The present invention relates to a technique for improving a glass substrate packing apparatus for packing a glass substrate when the glass substrate is stored, transported or transported.

  As is well known, when storing glass substrates for various image display devices such as liquid crystal displays, plasma displays, electroluminescence displays, field emission displays (hereinafter simply referred to as glass substrates), a plurality of glass substrates are used. It is customary to store and hold in a laminated state in a glass substrate packing device (hereinafter also simply referred to as a packing device).

  As this type of packing device, for example, as disclosed in Patent Document 1 below, a plurality of laminated glass sheets including a base portion and a back support portion that is erected and fixed on the base portion. It is publicly known that a substrate is placed in a vertical posture on a base portion so as to lean against the back support portion, and the front side of the laminated glass substrate in that state is pressed and held to the back support portion side. ing.

  In this type of packing apparatus, both when the glass substrate is loaded on the base portion during packing and when the glass substrate is taken out from the base portion during unpacking, both are erected and fixed on the base portion. Work is performed from the same side with respect to the back support.

Japanese Patent No. 2758561

  By the way, this type of glass substrate is required to have high quality in terms of surface quality. In particular, the surface quality of the surface on which the film is formed (hereinafter referred to as a guarantee surface) is required to have high quality that satisfies its smoothness, cleanliness, etc. under more severe conditions. In recent years, image display devices typified by liquid crystal displays have been improved in definition, and accordingly, the above demands on glass substrates have been more severely demanded.

  As a matter of course, the glass substrate surface on the guarantee surface side needs to maintain a high quality that satisfies the above requirements, so that a vacuum pad or the like can be brought into contact during packing and unpacking. Therefore, both when loading the glass substrate into the packing device during packing and when removing the glass substrate from the packing device during unpacking, work by adsorbing and holding the non-guaranteed glass substrate surface with a vacuum pad. Done. Therefore, in the packaging device as disclosed in the above-mentioned Patent Document 1, the guarantee surface of the glass substrate is placed on the back of the packaging device so that the non-guaranteed surface of the glass substrate can be sucked and held even when unpacked. It is sequentially loaded in a state facing the club side.

  However, in this type of glass substrate, the surface serving as the guarantee surface may be changed between one glass substrate and another glass substrate in a continuous molding process. As a specific example, when this type of glass substrate is molded by the downdraw method, even a slight change in molding conditions and changes in the surrounding environment over time have a large effect on the surface quality, The surface of the molded glass substrate may be different in surface quality between one surface and the other surface. In this case, the surface on the side that is excellent in surface quality from time to time is used as the guarantee surface, and the guarantee surface of the glass substrate may be changed from one surface to the other during the molding process.

  In general, this type of glass substrate is cut into a predetermined length, and is then wrapped in a packing device that holds the non-guaranteed surface side in a vertical state and stands by at a predetermined position. Therefore, in the packaging device as disclosed in Patent Document 1 described above, when the side serving as the guarantee surface of the glass substrate is changed from one surface to the other surface, the guarantee surface of the glass substrate is used as the back support portion. For example, the glass substrate is rotated 180 degrees in the horizontal direction with the non-guaranteed surface of the glass substrate being sucked and held, or the direction of the packing device itself is set in the horizontal direction. There is a problem that the glass substrate must be rotated 180 degrees, the glass substrate loading operation is unduly complicated, and the working efficiency is deteriorated.

  Moreover, since the enlargement of the glass substrate has been promoted in recent years, not only securing the rotation occupied space of the glass substrate in the production line, but also stably rotating the large glass substrate by holding only one surface thereof itself. May become difficult, and the problem of deterioration in work efficiency may become more prominent. In addition, the packing device for packing a large glass substrate is also forced to increase in size and weight, so that there is a problem of securing a rotation occupation space as in the case of a glass substrate, and a heavy weight packing. There is also a problem that a rotating device for rotating the device has to be additionally provided.

  An object of the present invention is to provide a glass substrate packaging device capable of easily and appropriately performing packaging and unpacking operations of such a glass substrate even when the surface on the glass substrate that can serve as a guarantee surface is changed. It is to provide.

  In order to solve the above problems, the present invention provides a plurality of glass substrates stacked in a vertical posture while detachably standing a pair of opposing support portions on a base portion. A glass substrate packaging device is provided, wherein the glass substrate packaging device is sandwiched between a pair of support portions from both sides in the glass substrate lamination direction and held on the base portion.

  According to such a configuration, since the pair of support portions opposed to each other on the base portion are detachably erected, the glass substrate at the time of unpacking can be removed by removing one of the support portions. Can be taken out from either side. In other words, no matter which surface of the glass substrate is guaranteed, unpacking the glass substrate from its non-guaranteed surface side by removing the support on the opposite side of the glass substrate. Can do. Therefore, even if any surface of the glass substrate is handled as a guarantee surface, the packaging operation and the unpacking operation of the glass substrate can be performed easily and appropriately.

  Said structure WHEREIN: It is preferable to further provide the positioning part which hold | maintains the said support part in the state positioned in the arbitrary position of the said glass substrate lamination direction.

  In this way, even when the number of laminated glass substrates is changed, the positioning unit can position and hold the support unit at an arbitrary position in the glass substrate laminating direction according to the end surface of the laminated glass substrate. It becomes possible to do. Therefore, regardless of the number of laminated glass substrates, it is possible to easily and appropriately ensure a state in which the laminated glass substrates are held by the pair of support portions from both sides. In this case, if necessary, the positioning portion can be configured to be detachable from the base portion in the same manner as the support portion.

  Further, in the above configuration, the glass substrate contact surface of the support portion is preferably a vertical surface.

In this way, since the plurality of laminated glass substrates are held in a vertical posture by the pair of support portions, each glass substrate is substantially free from the weight of the other glass substrate,
Generation | occurrence | production of the failure | damage of a glass substrate and a crack defect can be reduced.

  Moreover, said structure WHEREIN: The glass substrate contact surface of the said support part is good also as a plate surface which can contact | abut on the whole surface of the said glass substrate.

  In this way, even when a thin glass substrate such as a glass substrate for a liquid crystal display is to be packaged, both end surfaces in the stacking direction of the stacked glass substrates are brought into contact with each other by the support portions. Therefore, the glass substrate can be prevented from being bent, and a stable packing state can be maintained.

  As described above, according to the present invention, since the pair of support portions that sandwich the laminated glass substrate from both sides are erected in a detachable manner with respect to the base portion, from any support portion side. Since the glass substrate can be unpacked, the glass substrate can be rotated or the packaging device itself can be rotated in order to load the surface that can serve as a guarantee surface of the glass substrate toward the specific support side when packing. No complicated work is required. That is, even when any surface of the glass substrate is treated as a guarantee surface, one of the pair of support portions is removed from the base portion during the packing operation, and the glass substrate of the pair of support portions is unpacked. By removing the support portion on the opposite side of the guarantee surface side from the base portion, the glass substrate can be easily and accurately packed and unpacked.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  First, based on the schematic perspective view shown in FIG. 1, the whole structure of the packing apparatus which concerns on one Embodiment of this invention is demonstrated. As shown in the figure, the packaging device 1 is detachably provided with a plurality of glass substrates G stacked in a vertical posture on a base unit 2 so as to face each other on the base unit 2. It is comprised so that it may hold | maintain in the state clamped from the both sides of the glass substrate lamination direction by a pair of support part 3 which was added. At this time, the support portions 3 were positioned in the glass substrate stacking direction by the positioning portions 4 attached to the support portions 3 so as to contact both end surfaces of the stacked glass substrates G in the glass substrate stacking direction. Is held in a state. In order to prevent the glass substrate G from being damaged, a slip sheet is interposed between the plurality of laminated glass substrates G. For the same reason, a buffer member made of foamed resin, for example, is attached in advance to a region of the base portion 2 and both support portions 3 where the glass substrate G abuts.

  In the present embodiment, the base part 2 has a substantially rectangular horizontal surface on the upper surface, and a pair of back frame parts 5 are detachably provided so as to face both ends in the glass substrate stacking direction. Each of the two back frame parts 5 is connected by the bridge | crosslinking crosspiece 6 in the center position of the both ends up-down direction. And on this base part 2, both the support parts 3 and both the positioning parts 4 are assembled | attached by the aspect demonstrated below. The support portions 3 and the positioning portions 4 are symmetrically disposed on both sides in the glass substrate stacking direction via the glass substrates G stacked on the base portion 2, and both the support portions 3 and the both positioning portions 4 are disposed. Since the positioning unit 4 has the same configuration, only the support unit 3 positioned on one side of the glass substrate G and the positioning unit 4 will be described below.

  The support portion 3 is configured such that a plate-like body having a plate surface equal to or larger than the plate surface of the glass substrate G to be packed is detachably provided on the upper surface of the base unit 2. Therefore, the glass substrate contact surface 3 a that contacts the glass substrate G of the support portion 3 is configured to contact the entire surface of the laminated glass substrate G.

Further, the positioning portion 4 is disposed on the glass substrate non-contact surface 3 b side opposite to the glass substrate contact surface 3 a of the support portion 3. The positioning portion 4 is paired with the first positioning member 4a that is in contact with the approximate center of the glass substrate non-contact surface 3b of the support portion 3 and both ends in the width direction of the glass substrate non-contact surface 3b of the support portion 3. It is comprised from the 2nd positioning member 4b contact | abutted.

  One end side of the first positioning member 4 a is fixed to the approximate center of the back frame portion 5, and the other end side expands and contracts in the glass substrate stacking direction and comes into contact with the approximate center of the glass substrate non-contact surface 3 b of the support portion 3. It is comprised from the expansion-contraction mechanism, In this embodiment, the well-known pantograph jack generally used is employ | adopted.

  On the other hand, the second positioning member 4b extends in the vertical direction continuously from the placement portion 4b1 placed on the base portion 2 and the end of the placement portion 4b1 on the support portion 3 side. 3 is formed of a contact portion 4b2 that is in contact with the lower end portion of the glass substrate non-contact surface 3b in a substantially central position in the vertical direction.

  Specifically, as shown in FIG. 2, the mounting portion 4 b 1 of the second positioning member 4 b is a substantially rectangular plate-like body, and long holes 7 that are long in the glass substrate stacking direction are formed at both ends in the width direction. On the base portion 2, a plurality of screw holes 8 are formed at a predetermined pitch along the glass substrate laminating direction at positions that coincide with the long holes 7 of the mounting portion 4b1 in the width direction. Therefore, the long hole 7 of the mounting part 4b1 and the arbitrary screw hole 8 on the base part 2 are communicated, and a screw (not shown) is screwed into the screw hole 8 from above through the long hole 7 of the mounting part 4b1. Thus, the second positioning member 4b can be fixed at an arbitrary position in the glass substrate stacking direction. Further, the mounting portion 4b1 is connected to a U-shaped member 9 erected in an end region in the glass substrate stacking direction on the base portion 2 via a fine adjustment bolt 10 for fine adjustment. The position of the second positioning member 4b in the glass substrate stacking direction can be finely adjusted according to the rotation direction and the rotation amount of the bolt 10.

  On the other hand, as shown in FIG. 1, the contact portion 4b2 of the second positioning member 4b has a plate-like body framed in a rectangular shape standing in a vertical posture at the end of the mounting portion 4b1 on the support portion 3 side. Is. Therefore, the support part 3 against which the contact part 4b2 comes into contact is held in a vertical posture on the base part 2, and as a result, the glass substrate G is also held in the vertical position on the base part 2. .

  Next, a glass substrate packing method and an unpacking method by the packing device 1 according to an embodiment of the present invention will be described.

  First, when packing the glass substrate G, as shown in FIG. 3, the support portion 3, the positioning portion 4, and the back frame portion 5 on either side in the glass substrate lamination direction are removed from the base portion 2. Then, a plurality of glass substrates G are stood on the glass substrate contact surface 3 a of the other support portion 3 erected on the base portion 2 in sequence between the glass substrates G via interleaving paper. Laminate. At this time, the surface serving as the guarantee surface of the plurality of glass substrates G may face any direction of the glass substrate lamination direction as long as the orientation of the laminated glass substrates is uniform. In the illustrated example, the base portion 2 is mounted on the pedestal 11 having an inclined surface inclined in the glass substrate stacking direction so that the glass substrate G can be easily stood on the support portion 3 during the loading operation of the glass substrate G. However, depending on the size and thickness of the laminated glass substrate G, even if the loading operation of the glass substrate G is performed in a state where the base portion 2 is directly placed on the ground without using the base 11. Good. The same applies to the unpacking operation of the glass substrate G described later.

After loading a predetermined number of glass substrates G, the support part 3 on one side, the positioning part 4 and the back frame part 5 which have been removed are attached to the base part 2. At this time, the support unit 3 newly attached on the base unit 2 is positioned in the glass substrate stacking direction so that the positioning unit 4 accurately supports the end surfaces of the stacked glass substrates G in the glass substrate stacking direction. Positioning is done. As a result, the laminated glass substrates G are held in a state of being sandwiched by both support portions 3 from both sides of the glass substrate lamination direction, and the packaging operation of the glass substrates G is completed. In addition, according to the situation of storage, transfer, transportation, etc., the whole packing apparatus 1 which completed the packing operation | work of the glass substrate G is further covered with a jacket bag, a stretch film, etc.

  On the other hand, during the unpacking operation of the glass substrate G, of the pair of support portions 3 sandwiching the glass substrate G from both sides, the support portion 3 on the side opposite to the guarantee surface of the glass substrate G, the positioning portion 4, and the back frame portion 5 is removed from the base part 2, and the glass substrate G is taken out from the non-guaranteed surface side of the glass substrate G (see FIG. 3). Specifically, the non-guaranteed surface of the glass substrate G can be easily taken out by bringing the non-guaranteed surface of the glass substrate G into contact with the guaranteed surface of the glass substrate G by, for example, a vacuum pad.

  As described above, according to the packaging device 1 according to the present embodiment, the pair of support portions 3 that sandwich the laminated glass substrate G from both sides are erected detachably from the base portion 2 together. For this reason, for example, the glass substrate G is rotated in order to load the surface that can serve as the guarantee surface of the glass substrate G at the time of packing toward the one support portion 3 that is erected on the base portion 2 at the time of packing operation. The packaging and unpacking operations of the glass substrate G can be performed easily and accurately even when any surface of the glass substrate G is treated as a guarantee surface without requiring a complicated operation of rotating the packaging device itself. Can be done.

  In addition, this invention is not limited to the said embodiment, Various deformation | transformation as shown below are possible.

  For example, in the above embodiment, the positioning unit 4 is configured by the first positioning member 4a and the second positioning member 4b. However, the positioning unit 4 is the first positioning member 4a or the second positioning member 4b. It can also be comprised only by either one. In addition, the number of positioning members constituting the positioning unit 4 can be appropriately changed within a range in which the support unit 3 can be properly positioned in the glass substrate stacking direction.
